Eccleston (Doctor Who) is scientist Charlie Stoddart - who works at the Fortitude Arctic Research Centre - with Treadaway as his new colleague Vincent Rattrey and Call the Midwife star Raine as Jules Sutter, who is married to Frank Sutter (Pinnock), Fortitude's chief search and rescue pilot.

"Our audience loves great, world-class story-telling and so Fortitude is a perfect fit for Sky Atlantic," said Julia Barry, Director, Sky Atlantic. "We're thrilled to welcome Stanley Tucci - in his first British television role – and the rest of this amazing group of actors to the channel."

Fortitude has been devised by Low Winter Sun writer Simon Donald and will air on Sky Atlantic in late 2014.
